将字符串输入url-使用html表单和javascript

​ var currentPageURL=”http://api.hostip.info/get_html.php?ip=12.215.42.19&position=true"; var ip=getMeasurementsFromUrl（currentPageURL） 警报（ip）； 函数getMeasurementsFromUrl（ip） { var ipMeasurmentString=ip.substring（ip.lastIndexOf（'ip='））+3）； ipMeasurmentString=ipMeasurmentString.replace（&position=true），“”）； ipMeasurmentString=ipMeasurmentString.replace（“，”，”）； ipMeasurmentString=ipMeasurmentString.replace（“/”，”）； ipMeasurmentString=ipMeasurmentString.replace（“-”，”）； ipMeasurmentString=ipMeasurmentString.replace（“，”，”）； ipMeasurmentString=ipMeasurmentString.replace（“/”，”）； ipMeasurmentString=ipMeasurmentString.replace（“-”，”）； ipMeasurmentString= 返回ipMeasurmentString； } ​ 我试图编辑网址，使其读取输入的ip，到目前为止，我已经得到它读取的ip地址，目前有一个表单输入的ip

此外，如果有人有任何关于如何使表单更ip格式的提示，也会很有帮助

如果ip地址不变，您可以使用：

<p><input name="form[ip]" id="ip" class="ip" type="text" value="Enter IP here" />
</p>            
<p><input type="submit" value="Submit" /></p> ​   


var currentPageURL = "http://api.hostip.info/get_html.php?ip=12.215.42.19&position=true";
var ip = getMeasurementsFromUrl(currentPageURL)

alert(ip);

function getMeasurementsFromUrl(ip)
{

var ipMeasurmentString = ip.substring(ip.lastIndexOf('ip=')+3);

ipMeasurmentString =ipMeasurmentString.replace("&position=true",""); 
ipMeasurmentString =ipMeasurmentString.replace(",","."); 
ipMeasurmentString =ipMeasurmentString.replace("/","."); 
ipMeasurmentString =ipMeasurmentString.replace("-",".");
ipMeasurmentString =ipMeasurmentString.replace(",","."); 
ipMeasurmentString =ipMeasurmentString.replace("/","."); 
ipMeasurmentString =ipMeasurmentString.replace("-",".");
ipMeasurmentString =
return ipMeasurmentString;
}

如果发生变化，您可以尝试：

element = document.getElementById("ip");
var newstring = ipMeasurmentString.replace("ip=12.215.42.19&",element.value);

currentPageURL字符串是否已修复？或者它会改变吗？我正在尝试获取它，以便将输入的ip放入currentPageURL，然后将.php输出到html.Hi Greezer中，它会从inputform更改为ip

var part = str.split("ip=");
var newstring = part[0] + "ip=" + element.value + "&position=true"; //part[0] = text before the ip=
